There's some glitch that labels this as support for your argument, but I beg of you, BEG of you, how in the hell is Malcolm X's espousing of the view that African-Americans need to show strength and solidarity in the face of their persecution the same as David Duke's arguments for White Supremacy?
You do realize that by putting your argument in quote marks you suggest, to a more discerning reader, ironically, that you are satirizing the position of the fanatic you posted this in response to, right?
Whatever your point may be, it appears that you are satirizing the issue, so I support your response for that. It sounds as ridiculous as it would indeed be if you actually meant it.
You have some important and very insightful points, but you've missed the meaning behind many of the ones you've responded to, and that can make it appear that you are indeed coming from a position of "white indignation," though from many of your points that is obviously not the case. I suggest you read the man's post again.
